ABSTRACT:
A radiator includes two dipole elements as plate-shaped conductors. The radiator further includes two conductive line portions provided on opposite sides of a prescribed axis, sandwiching both of the two dipole elements, each having one end connected to one dipole element and the other end connected to the other dipole element. The two conductive line portions are formed to conform to the shapes of the dipole elements. As the conductive line portions having such shapes are connected to the dipole elements, better characteristics can be attained over wide frequency range and the size can be made smaller than the conventional radiator. Thus, an antenna having smaller size and improved characteristics can be provided.
